RE: SetEnvironmentVariable in Debug and Release cofiguratin

Tech-Archive recommends: Fix windows errors by optimizing your registry

>From the Platform SDK
--------------------------

Calling SetEnvironmentVariable has no effect on the system environment
variables. The user can add or modify system environment variables using the
Control Panel. To programmatically add or modify system environment
variables, add them to the
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session
Manager\Environment registry key, then broadcast a WM_SETTINGCHANGE message.
This allows applications, such as the shell, to pick up your updates.

So, my next question is this ... how are you checking for your environment
variable, are you doing it programatically (calling GetEnvironmentVariable)
or are you trying to find it in the EnvironmentVariables tab of the control
panel, etc.

You will not be able to see the variable in your system environment
variables (via the control panel) every PROCESS has an environment block that
contains a set of environment variables and their values, you will have to
inspect these environment variables programatically.

I hope that helps.

:o))
